Does GrapheneOS make upstream contributions?
+ +GrapheneOS has made substantial contributions to the privacy and security of + the Android Open Source Project, along with contributions to the Linux kernel, + LLVM, OpenBSD and other projects. Much of our past work is no longer part of the + downstream GrapheneOS project because we've successfully landed many patches + upstream. We've had even more success with making suggestions and participating in + design discussions to steer things in the direction we want. Many upstream changes + in AOSP such as removing app access to low-level process, network, timing and + profiling information originated in the GrapheneOS project. The needs of the + upstream projects are often different from ours, so they'll often reimplement the + features in a more flexible way. We've almost always been able to move to using + the upstream features and even when we still need our own implementation it helps + to have the concepts/restrictions considered by the upstream project and apps + needing to be compatible with it. Getting features upstream often leads to an + improved user experience and app compatibility.
